Question

When a certain liquid freezes, it expands about 8.00%. What would be the pressure increase inside an engine block if the liquid in it froze? (The bulk modulus of the liquid when it solidifies is 1.70 109 N/m2.) answer in N/m2

Answer 1

Use \[B=\frac{\Delta P}{\Delta V / V_i} \] where B is bulk modulus, P is pressure and V is volume.
Solve for change in puressure and use the percent expansion to say that Vf is 1.08 Vi. \[ \Delta P=\frac{1.08V_i-Vi}{Vi}B=0.08B\]
